TX somehow in program mode?

So I’ve had the 1849 Journey for years and have not flown it once. The tx is in some weird program mode or diagnostic mode and will not connect to the drone. When I power up the tx both sets of red and green LED’s flash and when I press some random (to me) button sequence then press the normal/sport mode button it’ll beep once I press it again it beeps twice keep pressing to 8 and itll beep 8 times. If I hit the stunt button the connected chyme sounds and hit rth button the disconnect sound chyme is played. I doubt I’ll get a answer to this cause SV support is about as useful as a bull with teets. So hopfully someone on earth still flies these drones and has had similar problem. ?
Anyway heres to hoping.
Cheers

Sorry its when I press and hold down both right & left buttons at powerup not just a random button press. Also I can connect to the drone just fine thru the webap I can update the sonix and flight firmware but not the tx. I can see all the parameters test the motors etc but the front left and rear right are swapped !? And when I go into the camera options no playback is displayed on my pc like my 1736 does, it flashes “snapshot” on take photo option. I’m thinking something might be buggered on the sonix board ?
